About The Stitches Per Inch to Points Conversion Table
In embroidery, the term density refers to the distance between stitches in a satin or column stitch. Some software programs measure density using embroidery points. An embroidery point is equal to 1/10 of a millimeter. Other software programs measure density in stitches per inch by counting the amount of stitches in an inch of a column stitch.
